' This invention relates to" window hoists and the like) This"hoislt isparticularly intended to be used; forhoisting and dumping material intowindowsofbuildings which are under construction.

An {object of this'invention isto provide ehoist' whi'chfcan be quicklyandeasily applied to anopeliwindow. r

L XThese and other objec'ts,'a s will hereinafter appear, are acconiplishedby this invention which is fully described in 'theflfollowingspecification and shown in the accompanying drawings in which 1 Figurelisa vertical "section through a window opening showing the hoist'insideelevation; 1 i y Fig. 2is apartial enlarged vertical section on theline2 of Fi .11;' Fig. "3 is (l-partial vertical section on the ZFig. 4:isa partial perspective View ingpart of the main frame; :i'nd'" :3

' *Fig. his a partial enlarged section on the line 5 of Fig. l 1 .7 Theembodiment illustrated comprises essentially two frames one of which;lies with in'the window, while the other liesoutside of the window. Thejinner frame consistsof two vertical rods one'ateach side of the windowwhich are adaptedto rest uponthe' floor 11 of a room, and theserodscarry clips or thelike 12whereby a cross beam 13 conjsistingpreferablyofe pipe is located.

These eye bolts are pr de ithllsu s 23 y w ich eyamay as be tightened so as to clamp ithen innerjandouter frames firmly upon the window-opening. The transverse member 18 isprbvided with two spacedfslins 24 which Jere firmly securedinplacethereon together lateral 0 presses 25. by means of electrical welding orthe like. Theses slings are" made to eiiteiid some distance throughth-elwindow opening and are provided ontheirlowerfedges with parallelint-urned portions 221?, the sziine being k adapted to receive the.lpweriportions of a boom 26 whichpin crosssection is inidein the form ofanjinifefled ugasshownin Figy2.

bracket upon which ihounted. a" movable sheave" frame 29 which carriesseries "of rollers30and which. are adapted to roll upon v Theframe29,has dependingportionsf2i2 through which passes a central pin 31upon t which is; revolvably firiounted La hoisting sheave 32. Theboom26fas a whole, is slidto a hook 35 at the inner end of the boom,this chain being adapted to be secured through a turnbuckle 36 and ahook 37 to the floor joist 38.

A gravity-operated bucket 39 is provided with a bail 40 which iseccentrically mounted on the bucket by means of pivots 41 on two sides.These pivots, as shown in Fig. 1, are placed to the left of the centerof the bucket, so that the weight of the bucket alone, or of the bucketand contents, tends always to keep the bucket in the position shown inFig. 1, in which the stop 42 is in contact with the bail 40. A handle 43is provided for ease in operating the bucket, as will hereinafter bestated.

The bail 40 is secured to a suitable rope 44 which passes over thesheave 32 and down to a suitable hoisting drum (not shown). The sheaveframe 29 has an operating handle 45 pivotallysecured thereto at 46. Theouter end of this handle is bent down at47 and overlies a bolt 48 whichpasses through lugs .24 on the slings 24. This bolt is provided with awing-nut 49 by which the bolt may be tightened so as to firmly securethe slings 24 in adjusted position on the boom 26.

A bolt 48 striking the bent end 47 of the operating handle 45 serves: asan outer stop for the sheave frame 29. A clip 50 secured to theoperatinglever 45 provides aspace into which the bolt 48 falls, as shownin Fig. 3. 4

The operation. of this window hoist or derrick is asfollows: The methodof assembling the main frame in the window, as well as the method ofadjusting the boom 26 in the-sling 24 and then of anchoring this boom inplace, will be readily understood from the foregoing description.Assuming that the parts are inthe position shown in Fig. 1, andthat thebucket 39 which is filled withv mortar or the like has been raised tothe position shown in full lines, the operator grasps the extension 47of the operating lever 45 and lifts the lever so that theclip 50clearsthe bolt 48. He then draws in on the lever so as to bring it tothe position shown in dotted lines in Fig. 1, the sheave 32 thenassuming thedotted line position shown in this figure. The operatorthengrasps thehandle 43 on the bucket and tilts the bucket forward so thatit dumps throughthe open window onto the floor 11. A suitable receptacle(not shown) is usually provided where mortar'is thus-dumped. Theoperator then rocks the bucket 39 back and its weight retains it in thenormal position as shown in full lines. He then pushes the operating.lever 45 back to the position shown in Fig. 3, .theclip 50 riding.naturally. over the pin 48" and. dropping so asto lock the operatinglever thereon.

It will be seen that Ihave provided a very simple and efficient. form ofwindow hoist T which is readily adjustedto accommodate-itself to windowsof various size and height.

While I have shown and described but a single embodiment of myinvention, it is to be understood that it is capable of manymodifications. Changes, therefore, in the construction and arrangementmay be made which do not depart from the spirit and scope of theinvention as covered by the appended claims.

I claim:

1. A window hoist comprising a frame adapted to be secured to a windowopening, a boom of inverted U-shape crosssection, a pair of slingmembers carried by said frame and adapted to lie one on each side ofsaid boom andhaving i'nturned flanges adapted'to engage and support theboom, and a sheave frame movable in said boom.

,2. A window hoist comprising a frame adapted to be secured to a windowopening, a boom of inverted U-shape cross section, means carried by saidframe for supporting said boom intermediate the ends thereof, said boombeing adjustable endwise in said holding means.

3. In a hoisting device, spaced frame members, means adj ustablyconnecting said frame members to engage opposite side faces of a walladjacent an opening, a sling pivotally carried'by one of saidframemembers, a boom slidably mounted in said sling to extend on oppositesides of sa-idframe members, means adapted to secure said boom againstsliding movement" in said sling, means adjustably eonnecting'one endofsaid boom to the other frame member, a sheave block= movable towardandfrom the other end'of said boom, and means supported by the boomsecuring means for moving and securing said sheave block;

r 4. In a hoisting device, spaced frame members adapted to engageopposite side faces of a wall adjacent an opening, a sling pivotallycarried by one ofsaid frame members, a boom slidably mounted in saidsling, means adapted to secure said boom against sliding movement insaid sling, and means adjustably connecting the boom tothe other framemember.

5. In a hoisting device, spaced frame members adapted to engage oppositeside faces of a wall adjacent an-opening, a sling carried by one of saidframe members,a boom slidably carried by said sling, and meansadjustablyconnecting the boom to the other frame member.

6. In a hoisting device, a supporting frame, a sling pivotally carriedby said frame, a boomslidably adjustable in said sling, and meansadapted to secure said boom inaugular adjustment-about said sling pivot.

7. In a hoisting device, a supporting frame, asling carried bysaidframe, aboom of inverted U-shaped cross section carried by said sling,tracks carried within said boom, a

sheave block movable on said tracks, and

means movable through said boom and connected to said sheave block foradvancing, retracting and securing said sheave block.

8. In a hoisting device, a frame, a boom of'inverted U-shaped crosssection carried by the frame, and a sheave supporting and'operatingdevice movable within the boom and having an operating handle dependingfrom said boom. r

In testimony whereof, I have hereunto set my hand this 16th day of May,1928.
